P.O. Box 343
Apex, NC 27502
Dear Sirs:
You have our approval, in accordance with the attached conditions and those listed below, to impact 0.096 acres of
wetlands (0.087 acres permanent impact), 313 linear feet of streams (293 feet permanently) and 0.61 acre of stream
buffers for construction of the McGowan Creek subdivision at Efland-Cedar Grove Road in Efland, NC, as you
described in your application dated December 4, 2003. After reviewing your application, we have decided this fill is
covered by General Water Quality Certification Numbers 3374 and 3402. These certifications allow you to use
Nationwide Permit Numbers 12 and 39 when the Corps of Engineers issues them. This approval is also valid for the
Neuse River buffer rules (15A NCAC 2B .033). In addition, you should get any other federal, state or local permits
before you go ahead with your project including (but not limited to) Sediment and Erosion Control, Coastal Stormwater,
Non-Discharge and Water Supply Watershed regulations. This approval will expire when the accompanying 404 or
CAMA permit expires unless otherwise specified in the General Certification. This approval shall replace the
approval Issued on December 22, 2003.
This approval is only valid for the purpose and design that you described in your application except as modified
below. If you change your project, you must notify us and you may be required to send us a new application. If
the property is sold, the new owner must be given a copy of this Certification and approval letter and is thereby
responsible for complying with all conditions. If total wetland fills for this project (now or in the future) exceed one
acre, compensatory mitigation may be required as described in 15A NCAC 2H .0506 (h) (6) and (7). This approval
shall expire when the corresponding Nationwide Permit expires or as otherwise provided in the General
Certification. For this approval to be valid, you must follow the conditions listed in the attached certification and
any additional conditions listed below. Deed notifications or similar mechanisms shall be placed on all remaining
jurisdictional wetlands and waters to notify the state in order to assure compliance for future wetland and/or water
impact. These mechanisms shall be put in place within 30 days of the date of this letter or the issuance of the 404
Permit (whichever is later).
Conditions of Certification:
1. Upon completion of the project, the applicant shall complete and return the enclosed "Certification of
Completion Form" to notify,DWQ that all the work included in the 401 Certification has been completed. The
responsible party shall complete the attached form and return it to the 401/Wetlands Unit of the Division of
Water Quality.
2. A total of 293 feet of stream mitigation is required for this project. This mitigation may be debited from
mitigation done on the McGowan Creek tract as outlined in the April 11, 2003 letter from the Wetlands
Restoration Program (WRP).
We understand that you have chosen to donate 22.5 acres of easement (of a 40 acre easement Ecological
Enhancement Program (EEP) has previously offered to purchase) to the EEP in order to compensate for
these impacts to streams. In accordance with 15A NCAC 2R .0402, this contribution will satisfy our

compensatory mitigation requirements under 15A NCAC 2H .0506(h). According to 15A NCAC 2H .0506(h),
293 feet of restoration will be required from EEP. Mr. Ron Ferrell should be contacted at 919-733-5083 ext.
358 if you have any questions concerning EEP. For accounting purposes, this Certification authorizes
the fill of 293 feet of streams, in 030401 river and subbasin and 293 linear feet of stream restoration
are required. Please be aware that EEP rules require rounding of acreage amounts to one-quarter
acre increments (15A 2R.0503(b)).
The 22.5-acre easement shall be donated within one year of the initial impacts to the 293 feet of
stream. If the property is not donated by this time, then you shall contribute to the Wetlands
Restoration Fund to compensate for 293 feet of perennial stream impacts. This contribution shall be
made within thirteen (13) months of the initial stream impacts (if the 22.5-acre easement is not
donated). You are required to submit written notification to the DWO Wet/ands/401 Unit and Raleigh
Regional Office that the stream Impacts have begun within one month of the initial stream impact.
This notification shall include the date that the initial stream impact occurred. Once confirmed by the
DWO, this date will be used as the start date of your one-year allowance period to donate the 22.5-
acre easement.
3. The applicant is hereby notified that Orange County has been delegated the authority to issue approvals for
buffer impacts by the NC Environmental Management Commission. Mr. Renn Ivins (919-245-2588) should
be contacted for this approval to determine whether their approval from September 13, 2002 will need to be
modified.

Re: DWQ Project #02-1666

Mr. John Dorney
2321 Crabtree Blvd., Suite 250
Raleigh, NC 27604

Dear Mr. Dorney,

We recently received our approval of 401 Water Quality Certification for
DWQ Project #02-1666(McGowan Creek Subdivision) and would like to get some
clarification from you in regards to the "condition" of submitting a check to the
Wetland Restoration Program within one month of the date of this Certification and
prior to filling any wetland or stream.

As we indicated in our request, the proposed mitigation plan was for us to
donate 22.5 acres of easement (of a 40 acre easement NCWRP/EEP has
previously offered to purchase) to satisfy our mitigation.

We also request our time to satisfy the mitigation be tied to when ever
NCWRP/EEP is prepared to accept the easement from us and we request that we
be permitted to proceed with site development, including filling of wetlands/streams
immediately. We are prepared to convey the easement immediately but
understand that NCWRP/EEP has a process that may take some time and we have
no control over that.

I appreciate your consideration in this matter.

S' cerely,

Craig Morrison

DWQ Project 02-1666

Dear Mr. Dorney and Mr. Thomas: WATER QUALITY SECTION

On behalf of Efland LLC (property owner), we hereby request authorization from the US
Army Corps of Engineers to use Nationwide Permit 39 to cover permanent impacts and
Nationwide 12 to cover temporary impacts to stream channels and wetlands resulting
from construction of the proposed McGowan Creek development. We also request
confirmation from the NC Division of Water Quality (NC-DWQ) that the project
complies with the Neuse River Basin (NRB) buffer rules. A Pre-construction
Notification Application (PCN) is attached, which includes an agent authorization form.
A previous PCN was submitted to DWQ in August of 2002 but was returned due to
questions on stormwater and mitigation issues.
The proposed project consists of installation of infrastructure necessary to support a
single family lot development, such as roads, and on-site sewer service. It is located
3800'north of Hwy 70, west of SR1004 and east of SR1312. Please refer to the attached
map (Figure 1) for the location of the proposed project on a USGS topographic
quadrangle.

S&EC delineated the wetlands and jurisdictional waters present on the subject property in
the winter of 1996/1997. John Thomas of the USACE visited the site with Parker Sniffen
of Sear-Brown and Sear-Brown obtained a Neuse Buffer Rules Authorization Certificate
from Orange County on 9/13/02 (copy attached).

The proposed project involves four road crossings of perennial streams, two sanitary
sewer crossings of perennial streams, and one wetland. The stormwater plans are
attached from Sear-Brown and are based on input during meetings with Todd St. John of
DWQ. The table below itemizes and provides a description of each proposed impact to
waters of the US. Please refer to the attached Wetland and NRB Impact Map (7 sheets)
for the location of each impact. The original application required seven road crossings
and four utility crossings. This shows impacts have been minimized.

The USACE's current policy requires applicants to avoid and minimize wetland and
stream channel impacts to the maximum extent practicable and compensatory mitigation
to offset unavoidable losses of waters of the US when impacts exceed the thresholds for
notification (0.10 acre) or if a discharge causes the loss of any open waters. The
applicant has avoided and minimized impacts by redesign of the project. Compensatory
mitigation required by the USACE for this project will be made via donation of land to
NCWRP/EEP (see PCN and attached letter from NC Dept. of Administration for
explanation).

I

December 4, 2003
S&EC Project 96-2716.W0
Page 3

NC-DWQ's current policy requires mitigation for permanent stream channel impacts
over 150 linear feet of perennial stream. The stream channel impact (293' linear feet)
exceeds 150 linear feet so stream mitigation is required. Because the cumulative,
permanent impacts to wetlands, excluding stream channel impacts, (0.14 acre) are below
the 1 acre threshold, no wetland mitigation should be required. The sanitary sewer
crossings meet the WQC conditions, so S&EC believes that mitigation is not required for
utility impacts. Stream mitigation is proposed via donation of land to the NCWRP/EEP
(see attached PCN and letter from the NC Dept. of Administration for details).

Channels are subject to the NRB riparian buffer rule. All four of the road crossings have
been designed to cross the stream channels at a perpendicular angle to minimize impacts
to the riparian buffer. Additionally, each road crossing does not exceed 150 linear feet of
stream channel impact or 1/3 acre of riparian buffer. Please refer to the attached Wetland
and NRB Impact map for a detail of the riparian buffer impacts associated with each
crossing. Because the two sanitary sewer buffer crossings are perpendicular and impact
less than 40 linear feet of riparian buffer, they are classified as exempt activities in the
NRB riparian buffer rules. Current NC-DWQ policy allows road crossings without
mitigation if the impacts are less than or equal to 150 linear feet of stream channel or 1/3
of an acre of riparian buffer per tributary. Because project impacts to the riparian buffers
are within these thresholds, S&EC believes that riparian buffer mitigation should not be
required.
Sincerely,

VII. Impact Justification (Avoidance and Minimization)

Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
Roads and utility crossings are perpendicular to streams. Project was redesigned from the
original application to eliminate three road crossings and one utility crossing (on lots 2, 3, and
13). Site has limited areas suitable for septic systems utility crossings are required to access the
only usable areas on-site.

VIII. Mitigation

DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.

USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project, establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams, and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.

Page 9 of 12

If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
tittp:Hh2o.enr.state.nc.us/ncwetlands/sti-ni.s4ide.litnil.

1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
The NCWRP/EEP has offered to purchase up to 40 acres of land within this project from the
owner at $2600/acre The Corps has agreed to a 1:1 stream mitigation ratio. This would
equal $58,600 ($200 x 293') At $2600/acre this equals 22.5 acres. The owner proposes to
donate 22.5 acres to NCWRP and sell the balance to them as per their offer (see attached
4/ 1 1 /03 letter from NC Dept. of Administration and 5/6/03 e-mail to Ron Ferrell.

2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
(919) 733-5208 to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the

Ron,

This is a 40 acre wetland preservation tract that implementation and you approved last fall It is a
significant wetland meadow/marsh system that is quite We in the Piedmont. It was partially influenced
by historic mill operations and beaver. The site is comprised of the 7 lots listed below, but only the first
two lots border along McGowan Creek. All lots owned by Efland LLC with address of 124 Cobblestone
Drive, Chapel Hill, 27514. [For lot #2 only, Efland LLC has an address of 412 Constitution Drive,
Durham, NC 27705.]

Here is what Rich Shaw had to say about it:
"While we think a preservation project at this site has merits on its own, the map I sent also
shows you how the potential permanent protection of the wetlands and riparian areas associated with the
proposed
McGowan Creek subdivision would fit into a larger County scheme to protect the McGowan Creek
corridor as a
wildlife corridor and keeping the door open for a possible "rustic woodland trail" for community/public
use in
the future. The proposed trail could some day allow people to walk from the Efland-Cheeks community
school/park complex east
to the County-owned McGowan Creek Preserve-- a 63-acre site that the County purchased with Clean
Water Mgmt.
Trust Fund assistance in March 2000. From there, the trail might someday join future trails along the
Eno
River. So while there are no formal plans at this time, the County Planning Dept. and ERCD have a
desire to protect
this corridor for multiple objectives: to protect wetlands, a public water supply watershed, wildlife
corridor,
and community recreation/open space/pedestrian transportation. "
Right now, it is simply preservation with no public access. I have attached 2 photos for your use- one of
the site and the other showing the related efforts nearby. Let me know if you have additional questions.

Buffer Impacts to Tributaries of McGowan Creek (Classified WS-II, NSW)
Neuse Buffer Rules AUTHORIZATION CERTIFICATE

To Whom It May Concern:

Upon review of the proposed impacts to the protected riparian buffers on the
referenced site, Orange County has determined that the requirements for a "No Practical
Alternative" have been met. Thus, the County as local delegated authority grants this
Authorization Certificate approving the allowable uses described in your plan.
Specifically, you have been granted approval, in accordance with the conditions
listed below, to impact 17,294 sq. ft. of Zone 1 and 11,599 sq. ft. of Zone 2 of the protected
riparian buffers for the purpose of constructing road crossings across three tributary
streams AND 4034 sq. ft. of Zone 1 and 3024 sq. ft. of Zone 2 for the purpose of driveway
crossings across tributary streams. The utility impacts listed in the PCN applications are
exempt and do not require authorization. These impacts were described in the PCN
application and letter submitted to Orange County by Sear Brown consultants and dated
September 6, 2002. In addition, you should get any other required federal, state or local
permits before beginning the project, including (but not limited to) 404 Wetlands Permits,
401 Water Quality Certification, and Erosion and Sediment Control Permits.

Oct 20 03 10:06a Sear Brown 9197326676 p.3

This approval is only valid for the purpose and design described in your application
and attached site plans dated September 6, 2002. Any change to the project requires
notification to our Office and may require submittal of a new application. If ownership of
the property is transferred to another person(s) or entity, the new owner(s) will be
responsible for complying with all conditions of approval. You are required to supply a
copy of this Authorization Certificate and approval letter to the new owner as well. For
this approval to be valid, you must follow the conditions listed below as well as any other
conditions identified within 15A NCAC 2B .0233.

Conditions:
1. Diffuse flow of all stormwater at non-erosive velocities shall be obtained prior to
entering the protected stream buffers as identified within 15A NCAC 2B .0233.

If you do not accept any of the conditions of this certification, you may ask for an
adjudicatory hearing. You must act within 60 days of the date that you receive this letter.
To ask for a hearing, send a written petition, which conforms to Chapter 150B of the North
Carolina General Statutes to the Office of Administrative Hearings, P.O. Box 27447,
Raleigh, N.C. 27611-7447. This certification and its conditions are final and binding unless
you ask for a hearing.

This letter completes Orange County's review of the "No Practical Alternatives"
determination under 15A NCAC 2B.0233. If you have any questions or would like a copy
of the Neuse Buffer Rules or Orange County's Stormwater Ordinance, please feel free to
contact me at [phone]. Again, please note this letter does not authorize any impacts
to either Waters of the United States or Waters of the State. Contact the US Army Corps of
Engineers or NC Division of Water Quality if any impacts are proposed to either of these
waters.

Efland Site Evaluations
4/20/03

Perennial Evaluations were made at the following locations. In most of these features perennial reaches
appear to be avoided/minimized by moving the impact upstream.

Map (Impact) No. Coordinates _ Notes
This site is the western most site on this property. We looked at
this feature above a confluence of two first order channels. The
riparian forest at this location has been timbered approximately 3-
4 years ago, but the stream looked relatively stable with good
82-5 360542/791104 bed/bank characteristics and riffle pool sequences. There was lots
of storm damage. The stream was approximately 1 meter wide,
but had very low flow. The benthic fauna was dominated by
amphipods and isopods; however I also collected Pvcnopsyche
caddisfl , Capniids (stonefly) and salamanders which indicates a
perennial feature at this point.
Impact site 11 is below the confluence of two channels. I first
83- 11 360533/791110 looked at the impact area #4 which is upstream of #11 and
determined that it was perennial and therefore this section of
stream would be perennial as well.
This location apparently received enriched runoff from local
pasture area. The stream had fairly prolific growths of
filamentous algae and the benthos was dominated by tubificid
86-4 360538/791106 worms. The perennial call was made just below a bedrock grade
control feature approximately 100 feet above the confluence of
another stream and approximately 400 feet above impact #11. I
did collected Pvcnopsyche (caddisfly) and crayfish at this location.
This is a small tributary catchment that has a beaver
impoundment. I looked at the feature above the impoundment. it
85- 10 360531/791100 appears that there is some sping flow associated with this
catchment. The benthic population is dominated by amphipods
and isopods; however, I did collect some Leptophlebia (mayfly),
Ironoquia (caddisfly), Sphaerium (clam).
This is an obvious perennial channel. Very defined bed/bank
characteristics, riffle/pool sequences and very diverse benthic
87-9 360531/791052 fauna. I collected several types of mayflies, caddisflies and
crayfish. The site I collected these specimens at is approximately
150 feet below impact area #9, but I also looked at this channel at
impact area #3 as well.
This feature appears to be E/P. I collected Ironoquia (caddisfly) at
88-6 360528/791052 the spring seep. This site could be avoided by moving the impact
25 feet upstream. Crayfish were also collected at this site.
This is upstream of impact area #9. The stream at this point in
89-3 360539/791051 deeply incised but has good morphological characteristics and
perennial stream indicators including crayfish.

Parker,

I will be glad to meet with you about this project...
I looked over the file and noticed it is in a HQW watershed. I don't know if this was
discussed previously. As such stream mitigation is required for intermittent and
perennial streams (GC 3402 condition 5). Also, As for the arch culverts, please see
GC 3402, condition 1.
Finally - FYI, are you aware that this project may require a State Stormwater Permit
under 15 A NCAC 2H .1000? This project is tributary to McGowan Creek and just
upstream of Efland Mill Pond (Neuse Basin) and our file shows that as WS II, HQW
waters. As such, I suggest you contact Bradley Bennett in our Stormwater Unit to
determine whether or not you would be required to obtain a State Stormwater Permit if
you have not already.
thanks, Todd

Todd:

The landowner/developer of the McGowan Creek project desires to resubmit revised
construction plans and PCN applications to address John Dorney's written comments.
We are proposing to span multiple streams with arch culverts to reduce stream and
wetland impacts below the allowable threshold(s), thus precluding any mitigation.
Upon your recommendation, we had previously added level spreaders and stormwater
swales to provide diffuse flows into riparian buffers. We are considering an even
more extended system of roadside swales to achieve the same end.
I am requesting a meeting with DWQ to discuss our proposed solutions prior to
commencing with the actual stormwater design and calculations. Previously you had
a conference with our engineer, Stephen Ballentine on these issues, but Mr. Dorney
had written the original comments. Can you tell me who we need to meet with?
Thanks,

Dear Sirs:

On February 7, 2003 the Division of Water Quality (DWQ) was notified by receipt of your
additional information regarding your plan to fill wetland and streams in order to construct the
McGowan Creek Subdivision in Orange County. Approval from DWQ is required to disturb these
areas. Please provide 7 copies of the following information and refer to the DWQ # listed above in your
reply. In particular as described in 15A NCAC 2B .0502, we will require you to locate all streams and
ponds on the property. Please show these on maps of suitable scale (for instance 1" = 100 feet) so we
can begin to determine your projects' compliance with 15A NCAC 2H .0500.
More Information Requested:

1. Please show all wetland impact including fill slopes on the site plan. Sheet 2 indicates
wetlands impacts at impact site #'s 1, 6, & 10. These are listed in PCN as stream
impacts. Please clarify.

2. This Office believes that the driveway to access lot #2 can be moved or reconfigured to
avoid the impacts to the stream and wetland. Please revise the plans to avoid the impacts.

3. Mitigation for stream and wetland impacts may be required pending determination by the
USACE and the DWQ Raleigh Regional Office.

Level Spreaders:

1. The level spreaders do not appear to be designed per DWQ's Draft Level Spreader
Design Options and as such are not expected to achieve diffuse flow. (See
http://h2o.enr.state.ne.us/ncwetlands)

2. Some discharge points are directly into natural drainage ways. It is not anticipated that
diffuse flow would be achieved through the buffer.

3. You may want to consider the fact that if designed as grassed swales according to the NC
DENR Stormwater Best Management Practices Manual (available on the above web site),
the road side ditches would function to remove nitrogen precluding the need for level
spreaders.

Your project was initially received by this office on October 15, 2002, since that time, this Office
requested additional information on October 24 2002 and January 29, 2003. However, your most
recent (February 7, 2003) correspondence has still failed to provide adequate information necessary for
an appropriate review of this project. Therefore, we hereby return your application and will consider it
withdrawn since you have repeatedly failed to address the issues raised in our earlier letters. You may
choose to resubmit your application with a new fee with the additional information outlined earlier in
this letter with a new application fee and we will then begin processing it.

Thank you for your attention to this matter. If you have any questions please do not hesitate to

Re: McGowan Creek Road/Subdivision, DWQ #02-1666

Mr. Dorney:

Enclosed are seven copies of the construction plans for the McGowan Creek Road project. All streams
and ponds have been shown on sheet 2 of our plans at a scale of 1" = 200'. Periodically there is
additional ponding along McGowan Creek; this occurs within the floodplain shown.

The following addresses the comments of your letter to Efland, LLC dated October 24, 2002:

1. We have made extensive revisions to insure that the stormwater discharges will provide diffuse
flow through the buffers. The calculations to substantiate this are included on sheets 7 and 8 on
the plans.

2. We are aware that compensatory mitigation may be required for this project. We have
contacted USACE and the DWQ Raleigh Regional Office for site visits.

3. We have enclosed a check for an additional $275 review fee.

Please call me or email at parker.sniffen a,searbrown.com if you have any questions.

Attached is a Pre-Construction Notification Application for the McGowan Creek Road projec .
construction is shown on the plans titled "McGowan Creek Road" revised October 8, 2002. Also attached is a
vicinity map, a copy of the USGS map, the county soils survey, a copy of the Orange County Authorization
Certificate for the Neuse Basin riparian buffers, and seven sets of the construction plans. We have submitted the
same documents to John Thomas of the USACE.

The site is 224 acres in area. It is west of SR 1004 (Efland Cedar Grove Church Road). It is within the Neuse
basin. The average lot size is 13.4 acres. The proposed private road is gravel, graded to DOT specifications. We
have mapped all streams shown on USGS maps and the county soil survey maps. I have witnessed these
drainageways in the field. These lots are not subject to Orange County Subdivision Regulations due to their size.
The 80' stream buffers are voluntary.
We are requesting a review by your office to determine if there are any practicable alternatives to the road
design, or if any mitigation is necessary. The developer desires that the proposed future driveway and sewer
crossings be permitted in addition to the road, although they will be constructed on individual lots at an
undetermined later date. All potential stream impacts are included in the PCN and referenced by number on the
drawings.
Orange County has determined that impact of the roadway to riparian buffers are classified as allowable as the
impact to any individual branch is less than the 150' threshold. They have not required any mitigation. The
driveway crossings are also classified as allowable. The utility crossings are classified as exempt.

Based on the county's interpretation, we are not proposing any mitigation for stream impacts. If the 401 rules
measure impact thresholds differently, please advise us. We have met with representatives of the Orange County
Environment and Resource Conservation Department and the Wetland Restoration Program. The WRP is
interested in the wetlands along McGowan Creek and has begun evaluating them for preservation. However,
these wetlands are not being impacted by the proposed development. Debbie Edwards of the Raleigh Regulatory
Field office has informed us that a pre-submittal conference is not necessary and has asked us to submit the PCN
without Section VIII completed.
Please call me if you have any questions.

Sincerely,

Parker Sniffen, PLS

measures to be inspected regularly.

VIII. Mitigation

DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.

Page 9 of 12

USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.

If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.nc.us/ncwetlands/strrngide.html.

1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.

2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
[phone] to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at htti)://h2o.enr.state.nc.us/wry/index.htm. If use of
the NCWRP is proposed, please check the appropriate box on page three and provide the

Buffer Impacts to Tributaries of McGowan Creek (Classified WS-II, NSW)
Neuse Buffer Rules AUTHORIZATION CERTIFICATE

To Whom It May Concern:

Upon review of the proposed impacts to the protected riparian buffers on the
referenced site, Orange County has determined that the requirements for a "No Practical
Alternative" have been met. Thus, the County as local delegated authority grants this
Authorization Certificate approving the allowable uses described in your plan.

Specifically, you have been granted approval, in accordance with the conditions
listed below, to impact 17,294 sq. ft. of Zone 1 and 11,599 sq. ft. of Zone 2 of the protected
riparian buffers for the purpose of constructing road crossings across three tributary
streams AND 4034 sq. ft. of Zone 1 and 3024 sq. ft. of Zone 2 for the purpose of driveway
crossings across tributary streams. The utility impacts listed in the PCN applications are
exempt and do not require authorization. These impacts were described in the PCN
application and letter submitted to Orange County by Sear Brown consultants and dated
September 6, 2002. In addition, you should get any other required federal, state or local

permits before beginning the project, including (but not limited to) 404 Wetlands Permits,
401 Water Quality Certification, and Erosion and Sediment Control Permits.
